Remember that the laws establishing and protecting the rights of unions were a shaky truce made by governments afraid of being overthrown. They’re a way to pacify unions, give them what they want so they don’t get angry enough to start burning shit again
Those laws aren’t what makes unions possible, viable, or effective. Those laws exist because unions were so effective even without them
People act like they can’t unionize just because they live in America, or their state is Right to Work, or the company they work for is notoriously anti-union. But labor movements survived periods of being literally mowed down with machine guns by the US Army - so we don’t need to be scared off by a few posters
The fundamental power of a union comes from the fact that we outnumber them, and that the workplace doesn’t move without our labor. That power doesn’t need to be permitted and can’t be legislated away. So join a damn union!
